Heating Performance and Efficiency

The Matrix 2700 excels at heating larger rooms or open-concept homes up to 2,200 sq ft with its 80,000 BTU peak output and powerful included blower for even heat distribution. Optimum efficiency reaches 70%, and the ultra-low 1.2 g/h emissions make it one of the cleanest inserts in its class.

Burn dry, seasoned hardwood (16–20″ logs) for best results. Owners report comfortable 8-hour burns and major savings on heating bills compared to open fireplaces.

Design, Build Quality, and Ease of Use

The Matrix 2700 offers a generous panoramic glass window that stays clean thanks to the air-wash system. The single air-control lever and cool-touch handle keep operation simple and safe.

Built rugged with 3/16″ steel and full refractory lining, it radiates heat evenly. The included 176 CFM blower runs quietly yet effectively when the insert reaches temperature.

Installation and Safety Tips

The insert requires a masonry fireplace with minimum opening: 31¾” W x 27⅛” H x 22⅛” D. Needs a 6″ stainless steel liner and minimum 15 ft chimney height.

Not approved for mobile homes or factory-built fireplaces. Optional projection kits and fresh air intake available.
